React App SDK

Everything you love about Create React App plus server-side code support (SSR, GraphQL API, etc) and config overrides (Babel, Webpack, etc.). See the demo project.

React App SDK is intended to be used as a drop-in replacement for react-scripts NPM module. If you want to add server-side code into your application built with Create React App, all you have to do is to replace react-scripts dev dependency with react-app-tools plus provide one more entry point for Node.js as demonstrated below:

src/index.js - Client-side rendering

import React from 'react';
import ReactDOM from 'react-dom';
import App from './components/App';

ReactDOM.hydrate(<App />, document.getElementById('root'));

src/server/index.js - Server-side rendering and/or API endpoint

const path = require('path');
const express = require('express');
const React = require('react');
const ReactDOMServer = require('react-dom/server');
const App = require('../components/App');
const stats = require('./stats.json');

const app = express();

app.get('*', (req, res) => {
  res.send(`
    <html>
      <body>
        <div id="root">${ReactDOMServer.renderToString(<App />)}</div>
        ${stats.entrypoints.main.assets.map(
          src => `<script src="${src}"></script>`
        )}
      </body>
    </html>
  `);
});

if (process.env.NODE_ENV === 'production') {
  app.listen(process.env.PORT || 8080);
} else {
  module.exports.default = app;
}

You can launch the app in development mode by running:

$ npm install
$ npm start

Then open http://localhost:3000/ to see your app.
When you’re ready to deploy to production, create a minified bundle with npm run build.

npm start

Server-side rendering with React.js
How fast is React SSR?

How to Customize

Create webpack.config.js file in the root of your project that extends the default Webpack configuration. For example:

module.exports = () => {
  const [
    browserConfig,
    serverConfig,
  ] = require('react-app-tools/config/webpack');
  return [
    browserConfig,
    {
      ...serverConfig,
      plugins: {
        ...serverConfig.plugins.concat(
          new LimitChunkCountPlugin({ maxChunks: 1 })
        ),
      },
    },
  ];
};
